Abstract:
A video compression encoder which does not require a video frame buffer is disclosed. Without a frame buffer, incoming pixels can not be compared to pixels previously sent to the decoder. Instead, the disclosed encoder only stores check values for groups of pixels sent. If a group's check value has not changed, the encoder sends a command to the decoder not to change that pixel group. Also, without a frame buffer, an incoming video frame can not be captured and later sent to the decoder as network throughput permits. Instead, if throughput is insufficient to send an encoded group of pixels, the encoder leaves the check value for that group unchanged and sends a command instructing the decoder not to change those pixels. This defers updating that group until the next screen update is sent to the decoder. Grouping of pixels can be done in any fashion, for example; a group can be a single video line, a portion of a line, multiple lines or screen rectangles containing portions of multiple lines.

Method And System For A Light-Weight Mobile Computing Device
Methods and systems provide the wireless use of a desktop computer through a lightweight long-range mobile computing device with extended battery life and no writeable or user-accessible persistent data storage, such as a hard drive, which could be detrimental if lost. In one implementation, the light-weight mobile computing does not run a full operating system, thereby reducing overhead and increasing speed. The mobile computing device provides mobility while providing access to information on a desktop computer. Since some components of conventional laptops are not needed, it may be smaller and/or have lighter weight, and provide extended battery life, while providing greater security by avoiding the risk of data loss. These systems provide a lightweight mobile wireless KVM device (e.g., a small “notebook” computing device) to connect to desktop computers. These lightweight, mobile computing devices may provide “instant on” capabilities avoiding the start up time of normal laptop computers.

International Classification:
H04N 7/26
US Classification:
37524002, 382239, 375E07126, 709231
Abstract:
Methods and systems are provided that allow a user to remotely access another computer and view its desktop without regard to whether that desktop has a relatively static image typical of a computer desktop, or whether it is playing a video, such as from a DVD. Relatively static screens may be displayed along with full motion video in such systems. These systems may also provide for both short mouse lag time when full motion video is displayed. In one implementation, hardware and firmware captures and encodes the video from the remote computer, and software on the client computer decodes the encoded video and displays it to the user.
Method And System For Data Center Rack Brackets For Automatic Location Tracking Of Information Technology Components

International Classification:
G08B 5/22 G06F 17/30
US Classification:
340 81, 707E17005
Abstract:
Methods and systems provide the automatic tracking of the physical location of information technology components in a data center. These systems automatically identify where a given IT component, such as a server, router, switch or other device, is located. They automatically identify which slot the IT component is located in a given rack in the data center. They include “smart” brackets containing small ID chips attached to the rack-based IT components and a “smart” rack rail for detecting the brackets. Each smart bracket uniquely identifies the IT component to which it is attached. The smart rack rail identifies the slot of the rack in which the IT component resides and communicates with a microcontroller to relay the position information to a database.

Detection And Processing Of Preselected Image Blocks In A Kvm System
A method, operable in a keyboard, video, mouse (KVM) system in which multiple target computers connected to a KVM switch are accessible via the KVM switch by a remote computer connected to the KVM switch, each of the target computers having a video output, and in which one or more preselected images are each associated with corresponding actions, the method includes monitoring the video output of at least some of the target computers connected to the KVM switch to search for one of the preselected images in the video output; and when one of the preselected images is detected in a video output of one of the target computers, taking the corresponding actions associated with that image.
